COM+

[Mark Broadbent]

Im a little bit stuck/ confused. Im running through a demonstration example
whereby (following instructions) I have
1. Created a .NET dll Component which has be imported into COM+ using
regsvcs.
2. The .NET dll was added to GAC
3. A client application is written. The instructions mention to add a
reference to this component *but* I cant quite work out what exactly it
wants me to add the reference to.
For instance if I add the reference to the original (.net dll) project then
client works and compiles fine - but surely I am not using the COM+
component only the .net dll.
If I delete the local dll then client still works (but surely client is
using the GAC dll not the COM+ component)
If I instead try to add the reference (in my client project) to the
registered COM+ dll then I get the error "A reference to "StepByStep7_5"
could not be added. Converting the type library to a .NET assembly failed.
Type library StepByStep7_5 was exported from a CLR assembly and can not be
re-imported as a CLR assembly.

All I want to know/ do is be sure that my client is using the registered
COM+ component.

Any advice would be greatly appreciated!

Cheers.

P.S
How do I delete COM+ components too - I have deleted several thru component
services but many more old ones are still being listed in VS2003.net COM+
reference list.

That's not necessary.

Yes you are, if everything was done correctly. At the point where the client
code creates an instance of one of your objects, pull up the COM+ explorer.
They should be spinning.

Yes, but if the COM+ application still exists then that's what the client is
using. Again, COM+ and the GAC have nothing to do with each other.
If I instead try to add the reference (in my client project) to the
registered COM+ dll then I get the error "A reference to "StepByStep7_5"
could not be added. Converting the type library to a .NET assembly failed.
Type library StepByStep7_5 was exported from a CLR assembly and can not be
re-imported as a CLR assembly.
Which is to be expected =)

Hunt down all the copies of the typelibs and unregister them. Be careful;
that's how machines get borked in the first place.
